They were putting out a presidential fire today in New York. And no, Donald Trump was nowhere in sight.

Trump Tower, the mixed residential and business building that sometimes serves as the New York White House when the president is in town, had a fire on its 50th floor today. The four-alarm blaze at the 58-story building on Fifth Avenue at 57th Street in Midtown was quickly quelled, although not before debris from the blaze fell to the streets below.

Flames and billowing smoke were visible from the street, and one serious injury to a civilian was reported. Four firefighters had minor injuries.

The building was not evacuated, but some residents voluntarily left the building on their own. Some surrounding streets from Trump Tower were closed during the incident. No cause for the fire has been revealed as of yet.

Trump Tower is the headquarters of The Trump Organization. The president lives there in the top three floors when he is in New York. A minor fire also occurred on the buildings roof three months ago.

President Trump was in the White House, and U.S. Secret Service has been made aware of the incident,

Trump praised the buildings construction as a “well built building” and lauded firefighters who managed to put out the blaze on Saturday.

Fire at Trump Tower is out. Very confined (well built building). Firemen (and women) did a great job. THANK YOU!
